'Literal is rvalue' is very important semantics for strict typed languages.
A literal is not referenced from any other places, so it is _unique_ and
_thread_local_. This is necessary for good resource management.
(e.g. Unique!T, Scoped!T, etc.)

But now, In D we cannot create rvalue struct object 'in place'.
(Note: Returned rvalue from function might be moved, so it is not 'in place'.)
It looks to me like a serious flaw.
